Microsoft issues two security bulletins to address eight vulnerabilities in Windows and Microsoft Office. One specifically that impacts Excel, which could affect many businesses considering how frequently the application is used. The bulletins will impact fewer machines, almost avoiding all servers unless SharePoint Server 2007 is installed. Microsoft recommends users upgrade to IE 8, even as the company begins to share details around IE 9. Microsoft is continuing to investigate the “targeted attacks seeking to exploit this vulnerability,” but the company did not issue a patch yet.”]
